Current Grade Sheet

Required Text: Understandable Statistics: Concepts and Methods, WITH Web Assign by Brase & Brase 11th ed.

Prerequisite:            Three years of high school mathematics and an appropriate score on the Mathematics Placement Test or completion of MATH 1100 or MATH 1110 with a grade of B or better. 

Description:           A nontheoretical introduction to statistics with an emphasis on applications in a variety of disciplines. Topics include measures of central tendency, position and dispersion; basic probability; hypothesis testing; estimation; analysis of variance; linear correlation and regression; nonparametric statistics. Prerequisite: Three years of high school mathematics (including two years of algebra) and an appropriate score on the Mathematics Placement Test, or completion of MATH 1170 or higher.

Goals and objectives of the course:

Upon completion of this course, the student will be prepared to interpret and use statistics that they encounter both in connection with their discipline and in everyday life. The student will also be able to conduct basic statistical inference.

Homework:            Will prepare you for the quizzes and exams.  You are responsible for understanding how to do each problem; I recommend study groups of three to four. Each student is expected to attempt one of the homework questions at the board sometime during the semester.

Exams:            There will be three exams during the semester. The final exam will be Thursday, December 10th from 3:30 - 5:30 pm.

Grades:            Grades for this course will be based upon homework, quizzes, tests, and a comprehensive final exam; some of the quizzes may be unannounced.  Items for both will come from the assigned homework.  The following grading scale will be used to determine grades:

Make-ups are not allowed for missed quizzes, instead I will allow you to drop your lowest score.  All tests will count toward your final grade.  The instructor reserves the right to adjust the grading scale if necessary.

Working through the assigned problems is essential to learning mathematics.  Showing your work is the only way to receive partial credit; hence it is very important on quizzes and exams.
